Advanced Series

Title: Modular Arithmetic Part I

Speaker: Gregory Owen

Time & Date: 2pm-3pm Saturday March 28

Location: Princeton Public Library, teen room (3rd floor)

Abstract:

We’ll be discussing modular arithmetic, bases other than 10, and some introductory results in number theory. We’ll cover the basic rules of modular arithmetic and use these rules to establish divisibility tests (by the end of the class, you’ll be able to quickly say which of 321583691 or 321583692 is divisible by 3 and which by 11). This class will also lay the foundation for a second class I’ll teach later this semester, which will get into some really cool topics like base 2i, in which you can represent any complex number using only the digits 0-3.

Chili peppers: 1 out of 4.

Recreational Series

Title: Building a Geodesic Dome

Leader: Harini Subrahmanyam Fredrickson

Time & Date: 3:14pm – 4pm Saturday March 28

Location: Princeton Public Library, teen room (3rd floor)

Abstract: We will be engaging in a fun hands-on activity by creating a large geodesic dome. These can be found in many places in the world, such as the Epcot Center at Disney World!
